`Tourlljwhonzz'li'raag/ concern: .Be 1t .known that` I, JOSEPH BERG, Lacitil zen `of fthe United States, 'andresident lof Little Rock, inthe"county of Pulaski and `State of` Arkansas, have invented :certain newand `useful ImprovementsinGasEngine Starters, of which the `i'ol'lolWingis a speciiication.

This invention relates 'to devices der inanually starting fgaswengines,and fhas for its object Ato `provide improved `ineansdor safeguardingithe operator uin case of back lining.

. `It `iswthe aim `cnf this invention.Ato.nialre the automatic`releasing `mechanism as com- A pact as possible and `to protect itIfrom dust and tampering, as Well as insure its reliable operation. .1 ni i Another object isfto provide :improved and `simplified means forioclingthe starter so that it can 'not be used to turngonerfth engine byunauthorized*persons.` v `Other obj ects; Willi Fappear as theldescription proceeds. i i A The invention Will lirst` be hereinaiter``described in connection with thezaccompanying drawings, which constitutepart of @this specification, and then more specifically .delined in theclaims at the` end.` 0f the -description.
